  • Camimex (Cámara Minera de México) asks relevant authorities to contribute in the solution to the Peñasquito strike in Zacatecas, and to act more speedily on the granting of environmental permits needed.

ON EXPLORATION

  • Colibri Resource Corp. received the necessary permit to drill up to 2,000 m on the Evelyn property in Sonora. The program is focusing on the Main Zone and West El Sahuaro areas.
  • Monumental Minerals Corp. provided an update on the current drill program at the Jemi project in Coahuila. To date 1,800 m have been drilled targeting rare earth mineralization, with 12 holes completed and a final one underway, with results expected in about three weeks. “Numerous intrusive peralkaline dykes, sills, and veins, with identifiable eudialyte … were intersected in the completed holes … These peralkaline dykes and sills tend to occur in structural zones that appear to be adjacent to larger bodies of syenitic intrusions and are associated with irregular skarn mineralization at the contacts with the host carbonate sedimentary rocks. These zones are as much as several tens of meters in width downhole. The syenite may be the feeders for the peralkaline features (parental rocks) and pegmatitic intrusive rocks. Light rare earth element (LREE) bearing minerals such as monazite and xenotime have also been identified by visual inspection.”

(ON SOCIAL RESPONSIBILITY, Industrias Peñoles confirmed that it promotes a culture of environmental care in communities.

ON MEXICO ISSUES

  • Almadex Minerals Ltd., dropped several of its legacy projects in Mexico (Yago and Las Lajas projects in Nayarit and San Luis Potosi States respectively), “where exploration progress is challenged by numerous impediments to timely progress”.  
  • Galore Resources Inc., announced that due to some recent changes in the mining laws, enacted by the Mexican Government, Galore employed the services of a Law firm in Mexico to file an Amparo (injunction). “An Amparo is a constitutional remedy that protects individuals and entities against violations of their constitutional rights, in which this Amparo is the only legal remedy to challenge the constitutionality of the new mining laws.  In the case of the Mining Concessionaires, it is important to exercise this right and obtain a resolution to make sure the authority will respect rights of previous concessions”.
  • In 2022, the production of zinc, one of the six main metals that Mexico produces for its internal use and for export, was reduced because the federal authorities decided to reduce the operations of the mines. According to the Mexican Mining Chamber (CAMIMEX), the 2022 national mining production registered 744,324 tons, showing a decrease because in Zacatecas Newmont’s Peñasquito project reduced its tonnage to 34,473, while Fresnillo plc’s El Saucito project also limited its production to 9,054 tons less. In addition, the mines La Platosa owned by Excellon Resources, La Cienega owned by Fresnillo plc and Velardeña owned by Industrias Peñoles decreased their volumes by 40.6%, 15.5% and 4.6%, respectively. Chihuahua is another state whose production decreased with Grupo Mexico’s Santa Barbara project, which registered 20,696 tons, 11.5% lower than the previous year; and San Francisco del Oro from Minera Frisco with 17,923 tons, 4.3% less compared to 2021. Other states in which their mines decreased their production were: San Luis Potosí, with Charcas from Grupo Mexico, with an annual decrease of 16.4%; in Aguascalientes, Asientos of Minera Frisco, with 11.3%; in the State of Mexico, Tizapa with 5.9%, and in Guerrero with Capela, with 5.4%, both from Industrias Peñoles. Also, located in Guerrero, Luca Mining’s Campo Morado reduced its production by 23.2%. Zacatecas continued to be the most important, since its participation represented 48.4% of the national total and meant an increase of 1% compared to 2021. Durango was in second place in zinc mining production, but reduced its production by 2.2% in 2022 compared to 2021, due to lower production in Santiago Papasquiaro of 16.3%. While Chihuahua was positioned in third place, where production remained unchanged compared to 2021; the largest reduction in state tonnage was due to the municipality of San Francisco del Oro. “By company, Newmont was the largest national zinc producer in 2022, with a 23% share. The four most important companies of national origin that participate in the extraction of this metal are: Industrias Peñoles, Fresnillo plc, Grupo Mexico and Minera Frisco, which represented 50% of the total last year”, the document reiterates. CAMIMEX assured that there are projects that will boost the growth of zinc production in Mexico in the next five years and that, if they are taken advantage of, they could place Mexico among the top five producers worldwide. The foregoing would also mean a recovery of the industry after the impact of the pandemic and the impact on mineral prices. Among the main projects with this metal content in Mexico, Grupo Mexico’s Buenavista Zinc in Sonora stands out, as well as the San Nicolas development of Agnico Eagle-Teck in Zacatecas.

ON MEXICO ISSUE

  • Silver Tiger Metals Inc., was the only mining company reporting drilling intercepts in Mexico on the first week of April, 2023. Details are shown in the table below:

ON EXPLORATION

  • Colibri Resource Corporation reported assay results of sampling completed at its recently acquired El Plomo project in Sonora. Twenty-five grab samples returned values > 1.0 g/t Au, including 6 with values > 5 g/t Au. “A total of 62 grab samples taken by Colibri returned Au assay values > 0.1 g/t Au. Channel sample values range from 8.03 g/t Au to 0.089 g/t Au over sample lengths (true widths) of 1.7m to 0.1 m. The occurrence and general distribution of higher-grade samples (> 1.0 g/t Au) evident in the historical work was validated with the due diligence sampling”.
  • Prismo Metals Inc., released assay for 277 samples taken at its Los Pavitos project in Sonora, from which 175 samples collected at the Santa Cruz area returned 0.5 g/t Au or more (several with values above 5 g/t Au over widths of 0.20 to 1m, and the best returned 20.3 g/t Au over 0.6m), and seven samples returned over 100 g/t Ag.  Pathfinder elements As and Bi are also generally strongly anomalous. “At least six other target areas have been identified for additional detailed work to develop drilling targets for later this year. Drilling permits are in process and drilling is expected to begin in Q2 2023”.
  • Kingsmen Resources Ltd., expanded its land position at its Las Coloradas project in the southeast part of the Parral mining district in Chihuahua, with the acquisition of a new claim. The new 342 hectares claim is adjacent to its Las Coloradas project and covers prospective geology and structural and geophysical targets.
  • Monumental Minerals Corp., reported assay results and proposed drill targets from its flagship Jemi rare earth elements project in Coahuila. The company has completed four months of exploration consisting of detailed geological mapping, regional stream sediment sampling, ground radiometric geophysical surveys, and lithogeochemical sampling. “A total of 296 assays have been received for surface rock chip samples from Jemi Dykes and Veladora North. Samples that are both peralkaline and anomalous in REEs, Ta, and Nb (116 samples) define four discreet priority areas within Monumental’s mineral concessions”. “Three-dimensional modeling of airborne magnetic data indicates that a larger intrusive body and potential source for the mineralized dykes may lie at a shallow depth (less than 300 m) beneath the dykes. Based on these results, six preliminary drill targets have been chosen and a drilling program is anticipated to commence in June 2023”.
  • Minaurum Gold Inc., provided an update on its corporate strategy to develop and acquire a pipeline of potential Tier One precious metals projects, through a portfolio containing silver projects totaling 37,928 hectares; gold projects totaling 25,933 hectares; and copper projects totaling 12,856 hectares. “Key initiatives for each flagship project include: underground rehabilitation to be followed by mapping, sampling and underground drilling at its Alamos Silver project in Sonora. Results will serve as a basis for an initial resource estimate; at Santa Marta Copper-Gold Project in Oaxaca, an initial drill program has been designed and is awaiting a drill permit from SEMARNAT, the Mexican federal environmental permitting agency; and at Aurifero Gold Project in Sonora, a drill program to test deep targets has been designed and drill permits have been applied for, actively working to further consolidate the district.  Minaurum expects to advance the remainder of its projects through strategic joint ventures in exchange for a combination of royalties, carried interests, and payments such as it received in option agreements with Fortuna Silver Corp. and Infinitum Copper Corp”.

ON MINING

  • GoGold Resources Inc., reported Q1, 2023 production results from its Parral Tailings project in Chihuahua. The company produced 173.7K Oz Ag, 2,106 Oz Au, and 320.3K Lb Cu (400.1K Oz AgEq).

ON FINANCING

  • Golden Minerals Company announced that it is selling gold-rich pyrite concentrates from its Velardeña properties on improved terms to a buyer in Manzanillo. The Company had previously planned to construct a BIOX facility at Velardeña in order to recover the gold in the pyrite concentrate. The Company is now evaluating the economics of a restart of the Velardeña operation without the need for major capital expenditures for the BIOX facility and ancillary equipment. Golden made its first shipment of 142 tonnes of previously produced and stockpiled gold-rich pyrite concentrate under the new terms last week and is currently processing 3,000 tonnes of previously mined and stockpiled mineralized material from the Santa Juana mine for future shipments.

The Mining and Exploration News in Mexico: Highlights on the Fourth Week of February, 2023.

By Miguel A Heredia

During the 8th week of the year (February 20th to February 26th, 2023), at least 23 press releases were announced by companies working in Mexico, with ten reporting resources and developments of their properties, six communicating production and financial results, two informing on exploration results, two commenting on Mexican issues, one disclosing deals and corporate issues, one announcing financing issues, and one discussing social issues. ON MEXICO ISSUES, Almaden regretted the decision of Mexico´s Ministry of Economy to deny the two mineral title applications which were first made by Almaden in 2002 and 2008, and which in turn led to the grant of mineral titles in 2003 and 2009, respectively. GoGold, Bear Creek, GR Silver, and Guanajuato Silver reported the best drilling intercepts in Mexico on the fourth week of February, 2023. ON EXPLORATION, In Sonora, Tocvan released results from surface channel sampling of selected area for a bulk sample at its Pilar project.  In Coahuila, Monumental Minerals provided an update and defined drill targets at its Jemi Heavy Earth Rare Element project. ON MINING, Coeur reported Q4 and full year 2022 production and financial results from its Palmarejo mine in Chihuahua. Starcore announced Q3, 2023 production results from its San Martin mine in Queretaro. Equinox provided 2023 guidance for its Los Filos mine in Guerrero. Bear Creek announced 2023 production guidance for its Mercedes mine in Mexico. Gatos Silver released 2023 production and cost guidance for its Cerro Los Gatos mine in Chihuahua. First Majestic reported Q4 and full year 2022 production and financial results from their Mexican mine operations. ON FINANCING, Silver Tiger closed its previously announced bought deal offering for gross proceeds of approximately CAD $18M (El Tigre project, Sonora). ON RESOURCES AND DEVELOPMENT, GoGold reported additional drilling results from Los Ricos South, within the Eagle and Main Deposits in Jalisco. Guanajuato Silver announced drill results from its San Ignacio mine in Guanajuato. Alamos Gold reported Mineral Reserves and Resources for the year-ended 2022 at its Mulatos project, Sonora. Bear Creek released results of recent drilling from its Marianas and Rey de Oro deposits at its Mercedes mine in Sonora. Chesapeake announced updated Minera Resource Estimate for its world class Metates deposit in Durango.  Minera Alamos informed the commencement of drilling at its Santana project in Sonora. GR Silver reported underground drilling results from 35 holes drilled as part of the 2022 infill and exploratory drilling program conducted at its Plomosas project in Sinaloa. Silver Dollar identified five new mineralized target areas at its la Joya project in Durango. Regency Silver announced that two follow-up holes down-dip were completed at its Dios Padre project in Sonora. Vizsla provided a year-end 2022 summary of its activities carried out at its flagship Panuco project in Sinaloa.  ON DEALS AND CORPORATE ISSUES, Minera Alamos granted stock options to its management team, Board of Directors, and certain consultants (Santana project, Sonora).  ON SOCIAL RESPONSIBILITY, Almaden signed a cooperation agreement with the Ejido Santa Maria Zotoltepec, the ejido located closest to its Ixtaca project in Puebla.

ON MEXICO ISSUE

  • Almaden Minerals Ltd., regretted the decision of Mexico´s Ministry of Economy to deny the two mineral title applications which were first made by Almaden in 2002 and 2008, and which in turn led to the grant of mineral titles in 2003 and 2009, respectively. These mineral titles underpin the Ixtaca deposit which was discovered by Almaden in 2010. As previously reported, these mineral titles were reduced to application status as a result of an early 2022 decision of Mexico’s Supreme Court of Justice (SCJN). Almaden believes that this action by the Secretariat of Economy is inconsistent with the Mexican Mining Law, the SCJN decision, and international law. The Company expects to submit arguments challenging the Secretariat of Economy’s submissions to the District Court within the next few days.

  • Mammoth Resources Corp., presented results from six holes for a total of 620.7m from its 27 holes diamond drilling program at its Tenoriba project in Chihuahua. Highlights of the drilling include hole TEN21-22 collared on Carneritos Zone with 0.98 g/t Au and 10 g/t Ag (1.12 g/t AuEq) over 3m, and 0.57 g/t Au and 8 g/t Ag (0.68 g/t AuEq) over 10.5m; and hole TEN21 -24 with 1.14 g/t Au and 75 g/t Ag (1.13 g/t AuEq) over 39m, including 5.28 g/t Au and 13 g/t Ag (5.45 g/t AuEq) over 3m, including 1.45 g/t Au and 11 g/t Ag (1.60 g/t AuEq) over 9m, plus 0.46 g/t Au and 2 g/t Ag (0.48 g/t AuEq) over 42m, including 1.21 g/t Au and 5 g/t Ag (1.28 g/t AuEq) over 12m.  These six holes bring the total meters drilled in the recent phase to 3,244.25m in twenty seven holes.
  • Southern Empire Resources Corp., has initiated the field exploration program work on its recently optioned Centauro property. The company contracted PhotoSat Information Ltd  to provide maps of alteration mineral suites typically associated with epithermal precious metal deposits, using their proprietary processing methods for16 band WorldView-3 and high-resolution ASTER satellite optical spectral data. Results of the PhotoSat studies show significant trends highlighting argillic, sericite, and chlorite alteration. Southern also collected 396 soil samples  at 50m spacing along E-W lines, spaced 100-200m apart to cover a zone of prospective alteration and mineralization over 4km strike length. Assays are pending.
  • Monumental Minerals Corp., completed reconnaissance exploration program, which consisted of detailed geological mapping, regional stream sediment sampling, ground radiometric geophysical surveys, and lithogeochemical sampling to delineate discreet drill targets at its Jemi Rare Earth Element project. To date, 37 whole-rock analytic results from rocks collected at the Jemi project of which 11 have returned values greater than 0.15% total Rare Earth Oxide (TREO), including six samples that returned values greater than 0.23% TREO and up to 0.43% TREO. Results for 269 samples are still pending to arrive. Heavy rare earth oxide (HREO) values (include dysprosium (Dy) and terbium (Tb)), ranged between 1614 ppm and 39 ppm in peralkaline pegmatites, averaging 447 ppm. Six samples exceeded 680 ppm, including three that exceeded 830 ppm. Light rare earth oxides (LREO) values including neodymium (Nd) and praseodymium (Pr), returned values up to 0.26% and 0.23%, with values in trend with HREO concentrations suggesting similar REE-hosting phases in the peralkaline rock samples. “Geological mapping has confirmed that samples with the highest TREO and HREO values are from pegmatitic bodies. Three-dimensional airborne magnetics modeling show that surface pegmatite bodies are spatially associated with a numerous larger magnetic anomalies at depth that may represent potential source intrusions. Specific drill locations will target these pegmatites”.
  • Almadex Minerals Ltd., released results from the second hole drilled in 2022 at its San Pedro project in Jalisco.  Hole SP-22-004 intersected 846 /t Au over 1.3m. The current drilling program intends to better understand the orientation and distribution of the breccia zone so that further, more focused drilling can eventually be carried out.
  • Minaurum Gold Inc., provided an updated on its Taviche project in Oaxaca, which is under an option agreement with Fortuna Silver Corp. Fortuna is currently focused on the re-negotiation of surface rights to be followed by drill permits. “Review of historic data and field mapping over the last year identified the possible continuation of the Mezcal Fault for 3km to the northwest.  Drill targeting is in progress along the Mezcal Fault to test for both Mezcal-style gold mineralization and silver bonanza style mineralization associated with jasperoid-related mantos”.  Another goal is to develop additional concepts to test the potential at depth at the Cerro La  Mina Zone where a drill hole encountered 235 g/t Ag and 0.19 g/t Au over 46.3m.

ON MEXICO ISSUES

  • Vizsla Silver, GR Silver and Defiance Silver reported the best drilling intercepts in Mexico on the second week of August, 2022. Details are shown in the table below:
  • According to a report from the Secretariat of Labor and Social Security, in the last three years, 979 mine inspections have been carried out throughout the country, of which 387 have been carried out in the coal zone, which means that “39% of all the mining inspections that have been carried out in the coal zone of Sabinas (Sabinas, Nueva Rosita, Palau)”. In the coal region, in these three years, 27 mining operations have been closed; that is, 84% of all mine closures in the country, due to non-compliance with security measures; to date 15 remain in force. In addition, the Ministry of Economy has been informed of the existence of 12 concessions that presumably could have irregularities.
  • The General Directorate of Mines of the Ministry of Economy provisionally suspended the works on 10 mining concessions in Sabinas Coahuila, on August 11, until the employers or representatives of each of the work centers certify compliance with the measures dictated in each one of the respective files after the inspections carried out by the Ministry of Labor and Social Security (STPS). The then General Director of Mines did not proceed with the provisional suspension of the works, arguing that the STPS information on the 10 previously mentioned mining concessions did not coincide with the registry data held by the General Directorate of Mines. Considering this and other possible irregularities, the Directors of Mines and Obligations were dismissed last June with the purpose of investigating and, where appropriate, establishing the corresponding responsibilities.

ON EXPLORATION

  • Monumental Minerals Corp., announced results of a recently satellite multispectral interpretation covering its Jemi Heavy Rare Earth Elements project in Coahuila. The interpretation highlighted discreet areas that may host eudialyte-bearing dykes, veins, and disseminations. Eudialyte is a Na, Ca, Fe/Mn, Zr silicate mineral that can contain up to 10% Rare Earth Elements, and 12% ZrO2. The Aster satellite spectral data also identified several areas prospective for Cu-Zn-Pb-Ag carbonate replacement deposits.
  • Silver Wolf Exploration Ltd., released 155 grab sample results collected during the ongoing surface sample program at its Ana Maria project, Durango, which has returned some high-grade values of Ag, Pb, and Zn.  From the 155 samples collected by Silver Wolf, 30 returned values >100 g/t Ag, 73 returned > 0.5% Pb, and 59 returned > 0.5% Zn with peaks of 1,536 g/t Ag, 34% Pb, and 19.4% Zn.  These results combined with the anomalies generated in the geophysical and remote sensing surveys will provide a basis for prioritizing drill targets.
  • Defiance Silver Corp., provided an update on the 4,750m maiden drill program at its Lucita project, within its Zacatecas Silver property. Drilling has encountered multiple intercepts over 199 g/t Ag and individual high-grade silver intervals. Drilling highlights include hole DDLU-22-10 with 0.20 g/t Au and 264 g/t Ag over 3.05m, including 0.19 g/t Au and 668 g/t Ag over 0.77m, plus 0.37 g/t Au and 166 g/t Ag over 4.01m, including 0.57 g/t Au and 220 g/t Ag over 22.72m, including 1.13 g/t Au and 416 g/t Ag over 1.22m, plus 0.08 g/t Au and 235 g/t Ag over 2.25m, including 0.19 g/t Au and 737 g/t Ag over 0.53m, plus 0.03 g/t Au and 189 g/t Ag over 0.75m, plus 0.04 g/t Au and 108 g/t Ag over 0.88m; and hole  DDLU-22-13 with 0.04 g/t Au and 147 g/t Ag over 1.57m, plus 0.04 g/t Au and 150 g/t Ag over 2m, including 0.2 g/t Au and 843 g/t Ag over 0.3m, plus 0.09 g/t Au and 109 g/t Ag over 1.15m. “The inaugural drill program at Lucita central (Palenque vein system) confirmed the presence of high-grade, Fresnillo-style, low to intermediate-sulfidation epithermal silver mineralization, consisting of mainly of pyrargyrite (high-level sulfosalt) and silver sulfides that potentially indicate the higher-level setting of a zoned epithermal system. Follow-up drilling is planned for later this year at the newly discovered zones of mineralization at Palenque and Tahures”.

ON MEXICO ISSUE

  • Arcelor Mittal announced that the strike broke out by the National Union of Mining, Metallurgical, Steel and Similar Workers of the Mexican Republic will affect the economy of Michoacan and the metallurgical sector. The strike will have an impact and serious consequences in the short, medium and long term on labor and economic stability in the Lázaro Cárdenas region, in the state of Michoacán, in the production chain and in the country´s economy.
  • With strike, Napoleón Gómez Urrutia and his miners managed to jump the “cap” in the payment of utilities. With the work stoppage carried out by mining workers from section 271 in Lázaro Cárdenas Michoacán to the company Arcelor Mittal Mexico, on June 15, they managed to eliminate the “cap” on the payment of utilities that was included with the labor reform in April of 2021. This is not the first union organization to take action to pressure the company to grant a higher amount in the payment of utilities.
  • The first International Mining Women’s Day was commemorated. This June 15 marks the first World Mining Women’s Day as an initiative of the International Organization “Women in Mining”. Engaging the Women Mining Community, the International Day of Women in Mining will showcase the experiences, hopes and aspirations about the industry, and celebrate the personal achievements of women in the industry.
